Unlike all the other Views, Whiteboard views cannot be moved to a different Space.
Could not confirm that, could you describe you case in more details or send attach a gif or video, thanks.
Occasionally it works, but usually it does not.
How do you inline a video here?
If you want to drag a view into a space that is not expanded (or has no views) drag onto the space name. Don’t try dragging into a gap between the space and the one below (that would be the place to drag if you were reordering spaces).
Thanks. That is entirely too non-obvious.
I have asked a few time here, never gotten an answer
If you use a gif instead of a MP4 it will be automatically embedded just by dragging it.
Use a free tool like screentogif to capture your screen in a Gif format.
